Juno: Reserve some DDR-DRAM for secure use
This patch configures the TrustZone Controller in Juno to split
the 2GB DDR-DRAM memory at 0x80000000 into Secure and Non-Secure
regions:
- Secure DDR-DRAM: top 16 MB, except for the last 2 MB which are
used by the SCP for DDR retraining
- Non-Secure DDR-DRAM: remaining DRAM starting at base address
Build option PLAT_TSP_LOCATION selects the location of the secure
payload (BL3-2):
- 'tsram' : Trusted SRAM (default option)
- 'dram' : Secure region in the DDR-DRAM (set by the TrustZone
controller)
The MMU memory map has been updated to give BL2 permission to load
BL3-2 into the DDR-DRAM secure region.
Fixes ARM-software/tf-issues#233
